Hello, dear Suman,
it is very nice that you search for answers regarding your future plans in Germany. To have a good qualification is important to get a good job and have a qualitative life in this country. That's why it is good that you make thoughts about getting a profession. But before you start an apprenticeship, you have to make previous achievements.
One of the most important things is to know the German language on the level B2/C1. But there are other things you have to keep before your eyes. I think you want to get a so called Ausbildung-Duldung. From the 1.01.2020 there are new regulations for people searching refuge in Germany. I think your lawyer knows about them, but you can contact a co-worker of the mbeon.de group to get more information. On the other hand, there are other questions which has to be clarified to give you a proper answer.
That's why, please download the mbeon application from Google Play or App Store.
